2.2 EMI Filter
In order to comply with the EMC rules (electromagnetic compatibility), as standard the compressors of 134-I series are delivered together with their own EMI filter (loose). In table 2 you will find the matching between compressors and EMI filters. The installation of such filter is up to the customer, who however has to comply with the following prescriptions:

2.3 Instructions for inverter cooling
To provide the necessary cooling of the inverter, the customer has to arrange a tapping from the liquid line and spill it onto the compressor through its dedicated intake (see picture 2). We recommend to tap the refrigerant from the liquid line after the condenser and where you are sure the refrigerant is liquid only, independently on the load conditions. However a liquid filter has to be installed before spilling the liquid into the inverter heat exchanger.

• The EMI filter insulation class is IP00. Therefore its suitable protection has to be assured depending on the specific application.
• To get rid of the heating generated by the EMI filter, a proper ventilation of its box has to be provided.

Important Note: It is mandatory to shield the cables:
• Between electrical panel and control circuit terminal • Between EMI filter and inverter
Important Note: For the following shielded cables it is mandatory to comply with the following prescriptions:
3.4.1.1 Serial port configuration 3.4.1.2 Memory registers 3.4.1.3 Holding registers 3.4.1.4 Input registers 3.4.1.5 Coils registers 3.4.1.6 Slave ID number
For the compressors of 134-I series the cabling between electrical motor and inverter is made at RefComp factory. The following cablings have to be carried out by the customer instead:
